Application iled November 30,1917. Serial No. 204:,641.

In Ford cars theemergency'brakeihend lcver is et the left of the body in front of the driver in the left side end is connected with e transverse pivot rod from which lever arms extend et the ends for connection with the rods leading to the einer- No provision is made for compensation, the' pull rods being pulled eque-l distances when the hand lever operatcd. This prevents eliicient braking :is onebreke may catch while the other will not. 011e of the important objects of my invention is therefore to provide improved, brake actuating lever mechanism which is compensating. Another object is to provide for 'supporting such lever mechanism in e position to permit the hand lever to extend up to' be `et the right of the driver. Ann other object is to provide such construction that the supporting mechanism-for the hand lever may be secured entirely by means of bolts elready `present onrthe Ford car th'us eliminating the necessity of drilling other holes or providing special supports or fes-l tening menus. In accordance with my invention I fasten supporting brackets or plates "to the inner end of the Vtransmission case housing, using the same screws or lv-olts which fasten the universel drive shaft 'oint to the` transmission cese housing. his forms a, very rigid support in convenient positin-to rmit `the hand brake lever to be more at t e center of. the car in position to be operated with the right hand.

On the` accompanying drawing my irngency brakes.

vproved construction and arrangement Yis oleery`ilhistretedr.` On this drawingy receive the bolts a, b, c and d.

Figure 1 is a side view of the transmission case housing and engine housing showing my attachment applied, and

Fig. i). is en end elevational view. n A 10 .represents the transmission cese housing body and 11 the cover therefor, these two parts being connected together by bolts-12 passing through. `the flanges 13 and 14. 15 represents the liy Wheel housing, 1.6 the crunk; housing und i' the engine frame. `The drive shaft 18 is connected with. the transmission mechanism within the transmission .housing hy uniiv'ersnl coupling mechanism wl 'ch is held in place by a. cap 19 secured to the inner end of the transmission'housing ,liv means of ,four bolts a, b, c and d, These four bolts I utilize for also supporting. my l attachment. As shown, this attachment comprises two sin'lilar supporting` plates 20 and 2l which are substantially semi-circular to engage with the sides of these-nir spherical ccp 19, sind these plates have bolt holes for registering with the holes `which l To apply the plates el] that is necessary -is .toxremove these bolts and reapply them to includefthe plates. At the lower ends of these plates are bearing lugs or sleeves 22 and 23 respectively which pivot ai shaft 24. To ithe right end of this shaft is secured the hub 25 from which the emergenc brake handlever '26 extends upwardly, t provided in the floor 28 of the car for'fthe ever. Between the bearing .lugs 22 sind 23 the shaft 24 has secured vthereto thehub 29 from which the arm '80 extends downwardly end 31 in which the bar 32 is pivotedeby vmeans of arbolt or in 33. By 'mansof clevis fittings 34 endp the vehicle-broke pull rods 36 and 37 are pivoted toi'the'lar ends byl ins 38 and 39. With this' arrangef ment, w en thekbrake lever is swungfrear- Wsrdly,the arm' 30 will beswung forwardly and vterminates in the 'biff'mated Y the other brake until it becomes tightened, eliicient braking bein thus possible;

In order to lock tie brake lever in any position 1 provide ordinary ratchet locking mechanism comprising a suitable ratchet rack plate 40 and a ratchet pawl 41, the paw] being pivoted on the brake lever and connected with the grip fitting 42 by the rod 4.3. The rack member I use is of such shape that it can be applied Without requiring special support or securing meansI such as screws or bolts. The device shown is of U-shape, the one limb e being arcuate and in e vertical plane with its front end f in a horizontal lane to form a foot for resting on top of t e liange 14 of the transmission housing body 11, and this foot is provided with a bolt hole for registering with one of the bolt holes for the bolts 12 whichO secure the transmission case cover to the body. As shown, the bolt nearest the inner en ol' the transmission housing is utilized fo. receiving the ruck member. When thus secured the arcuate part of the limb c has its center at the center of shaft 24 on which the brake lever is secured and the pawl 4l is pivoted in position to engage with the teeth y'. To further secure the rack member its other limb h is extended laterally at its end to form a foot i which is provided with a bolt hole for receiving the bolt b which receives the supporting plate 2l for the shaft 24.

In the ordinary construction and arrangement of Ford cars a kick-olf lever or arm extends from the pivot rod to which the emergency brake arm is secured, such kickoff arm serving to throw the high Speed clutch out of connection when the emergency brakes are locked. In my construction the kiclrol' arm or lever 44 is secured at its lower end to the left end of the shaft 24 and and at its upper end has a cam 45 for engaging with the abutment screw 46 on the clutch lever 47 which extends from the clutch shaft 48. If the high speed clutch is in when the emergency brake lever 26 is swung` to tighten the brakes, the arm 44 will swing` and bring its cam plate into engagement with the set screw to swing the clutch lever into neutral position.

My attachment is of simple and inexpensive construction. The same brake lever can be used and the only new parts necessary are the supporting plates 2O and 21 together with the shaft and the equalizer bar 32. vIt is unnecessary to drill new bolt or screw holes or to move or remove any of the vehicle parts. The plates 20 and 21 are merely slipped over the joint cap 19 in position to receive the bolts a, b, c and d, while the rack member is positioned to receive the bolt b and one of the bolts 12. When the nuts are applied to these bolts the attachment is in place and rigidly secured. The brake pull rods are then pivoted to the ends of the equalizer' bar 32 and the attachment is ready for operation. If the invention were utilized in the construction of Ford ears it would reduce the expense and create a e0nsidernble savingl for it would eliminate the special litt-ings which were necessa. in the o d construetionlx) su )port the bra (e lever pivot rod and would e iminate the labor necessary to drill holt holes :for these fittings and thel labor for a' plying the fittings. Furthermore, it woul permit placing the brake lever more in the center of the ear and away from the car door, making it then more convenient for entering or leaving the car at the drvers seat.

I do not desire to be limited to the exact construction and arrangement shown and described as changes are no doubt possible which would still come within the scope of the invention.

I claim as follows:
